LUBRICATOR.

Specification of Letters Patent.

Patented Mar. 330, 1915.

Application filed. March 16, 1914. Serial No. 825,084.

To all whom it may concern:

Be it known that we, DOUGLAS E. GAINER .and WVILLIAM L. STULL, citizens of the .United' States, residing at Brunswick, in the county of Frederick and State of Maryland, have invented certain new and'useful Improvements in Lubricators, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to lubricators and has for its object the production of a simple and efficient lubricator for use on locomotives and other parts of machinery which are desired or foundnecessary to lubricate. Another obJect of this invention is the production of a simple and efficient means for forcing the lubricant from the lubricating cylinders and also for facilitating the tions, constructions, and arrangements of parts as will be hereinafter fully described and claimed.

In the accompanying drawing :Figure l is a top plan view of the lubricator. Fig. 2 is a section taken on line 2-2, of Fig. 1. Fig. 3 is a top plan view of the central cylinder showing the manner in which the adjustable jaws are held in engagement with Fig. 4 is a section taken on line 41, of Fig. 3. Fig. 5 is a side elevation of the supporting bracket showing the manner in which the operating shaft is supported in engagement with the cylinders for feeding the lubricant. Fig. 6 is a section taken on line 6-6, of Fig. 1. Fig. 7 is an enlarged perspective view of the pinion adapted to rotate the feeding gear. Fig. 8 is an enlarged section taken through the pinion illustrated in Fig. 7 showing the manner in .The base 1 supports a plurality of cylinders or receptacles 3 over which extends a cover plate 4. The plate a carries a plurality of caps 4L which fit over the upper ends of the receptacle 3. The plate 1 also carries cap 5 which fits over the central cylinder 6, and this cap 5 is provided with a transversely extending channel portion 7 in which work the slidably mounted thread carrying blocks 8. The plate a is hinged to the support 5 in order to allow the plate to be swung off of the receptacle 3. A latch 6 is also carried by the plate 1 for holding the plate 4 in a set position. These blocks 8 are provided with laterally extending lugs 9 upon each side thereof, and these lugs 9 travel in the longitudinally extending slots 10 formed along the side of the channel portion 7 so as to constitute a means for regulating the slidable movement of the thread carrying blocks 8. These thread carrying blocks 8 are adapted to engage the threaded pins 11, which pins carry the milled thumb heads 12 for the purpose of facilitating the rota tion of the threaded pins 11 in order to move the thread carrying blocks 9 away from the threaded plunger 13 carried by the central receptacle or cylinder 5 as is illustrated in Fig. 2. The inner faces of the thread carrying blocks 8 are threaded as indicated at 1 1, and it should be understood that these blocks may be drawn away from the threaded plunger 13 to allow the entire plunger to be drawn vertically without the necessity of rotating the same in order to lift the plunger head 15 carried by the lower end of the plunger rod 13. The pins 11 extend beyond the side edge of the plate 4: as is illustrated in Fig. 1.

A gear 16 is mounted upon an annular upstanding ring 17 carried upon the top of the plate 4-, and this gear 16 is mounted upon the plunger 13 for moving the plunger 13 these teeth are adapted to be 7 engaged by the fingers 19 carried by the pinion 20. This pinion 20 is carried by a shaft 21, which shaftpasses through a sleeve 22 carried by the bracket 23. This bracket 2 8 be supported upon the supporting plate 2 1,111 any suitable manner so that the fingers 19 of the pinion 20,n1ay efficiently rotate the gear Wheel 16. The shaft 21 is provided with a ratchet surface'25 which surfaceis' engagedby means of the pawl 26 carried by th'e ratchet hee 27. The ate; wha e: is pfi of'vi'ded with "diverging 28, which arms are adapted tof be engaged by any suitabi'e operating means carried theehgine inachine with which the lubricatoris coopen-area. It shouldbe understood that any suitable me ns m y be einpld ed for operating the ratchet wheel J Th shat 2 1s provided with aplni ality (if notch portions 29 iipbri the periphery thereof'which portions are adapted to be i a bywhe p s p s p un e 3 0 mounted in the casing 131 so as to retard are rennet of the shaft-1'21 at each quarter ofatu rn. e I l L I The pinion 2Q comprises V snbstantially vertical body having substantially vshap'ed take n n n 2: 6 "n ?2d al'o er e P' riphery unrest The gear fingers 19 are placedfwithin'the pocket PDItiOIl'S 32 upon the 's"pporting pins- 33, which supporting Pin a mte by 7 f. he thumb 34in order that the, fingers 19 may he threw late the pockets 32 and held in Such position as to prevent the same from r'otating the gear 18. By means of having the fingers 19 supported upon the pinion 21 iiitheinahner as illustrated and described, it should'be understood that the feed o-fthe lubricant from the cylinders 3 and 5 may be regiilat'ed for the reason that allof the fingers 19 can be thrown outwardly so "as to have eaclrfinger rotate the gear 16 or'nlove the gear 316 the distance of four teeth at each revolution of the shaft 21. By having the ers 19 capable of being withdrawn in the pinion 20, it will be seen that the inion be so regulated as to cause the ear 16 to move either the distance of one, two, three, or four teeth at eachrevolution of the shaft 21,

' The pinion 20 carries a spring pressed plunger 32 "at the bottom of each socket 32 for the 'purpose of engaging the sockets formed upon the inner ends of the fingers '19. The plunger's 32 will c'on'stitnte an eflicient means for holding the fingers 19 in a set position. v A v e y The threaded plunger 13 is provided with a longitudinally extending groove 35 which engaged by 'a key 36 formed upon the 'gear wheel 16 so as toallow theplunger '35 to readil mete downwardly as the "gear 16 7 is rotated. Theplunger 35 is provided with n sheila he un d that by having 211%; the manner escri e that are ratchet wheel ma be freely rotated'in ene daemon without "rotating the shalft 21, but when rotated the opposite "direction the shaft befreely turned; V "It shojild be further uhdefrsto'od thata ver -si le and efficient means has been prodiicd whereby the-feedplungers be readily pulled to their normal pdsition by the removal (if the thread the ratchet wheel 27 inountediiipon the shaft ear-tying b1o'cks'8 out er hg'a emeht with I the plunger 13; p V 7 As is illustrated in Fig; 2 the threaded plunger 13 is provided with a reduced portion to allow the key carried the driving ear orayel therein and rotate without operating the plunger 13;.
